Highly stereoselective intermolecular oxy-michael addition reaction to alpha,beta-unsaturated malonate esters.
[reaction: see text] The highly diastereoselective oxy-Michael addition of the "naked" anion of (6S)-methyl delta lactol to alkylidiene-, arylidene-, and heteroarylidenemalonate derivatives leading to the direct formation of THP-protected beta-hydroxy ester derivatives is described. Subseq...

| Summary: | [reaction: see text] The highly diastereoselective oxy-Michael addition of the "naked" anion of (6S)-methyl delta lactol to alkylidiene-, arylidene-, and heteroarylidenemalonate derivatives leading to the direct formation of THP-protected beta-hydroxy ester derivatives is described. Subsequent acid-mediated deprotection affords the enantioenriched aldol products in quantitative yields. |
